Test Guidelines
getsentry/sentry-react-native
Enforce Sentry React Native SDK test conventions for naming, structure, mocking, and fixtures with Jest.
Test a CometChat React Native integration — mock the SDK for Jest unit tests, assert init-before-render ordering and no-Auth-Key-in-source, and use Detox for the flows only a device can prove.

What it does
Cometchat React Native Testing is an agent skill from cometchat/cometchat-skills. Test a CometChat React Native integration — mock the SDK for Jest unit tests, assert init-before-render ordering and no-Auth-Key-in-source, and use Detox for the flows only a device can prove. Triggers: test CometChat React Native, mock CometChat SDK jest, detox CometChat, unit test chat screen RN, CI tests for chat.
Its SKILL.md is about 1000 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: React Native =0.77; Jest; @testing-library/react-native; Detox (e2e)
It sits in Testing & QA, covering Unit testing and Cross-platform mobile apps. It works with CometChat, React Native and Jest. The repository describes itself as: Add CometChat chat & messaging and voice & video calls to any React, Next.js, React Native, Angular, Android, iOS, or Flutter project through your AI coding agent. Works with… The licence is MIT.
When your agent uses it
- Tasks that involve Unit testing
- Tasks that involve Cross-platform mobile apps
Example prompts
- “/cometchat-react-native-testing”
Requirements
- Node.js
- Compatibility (from SKILL.md): React Native >=0.77; Jest; @testing-library/react-native; Detox (e2e)
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Unmocked native peers — confusing NativeModule errors.
- Asserting kit internals — breaks on minor upgrades.
- Real credentials in tests — network flakes and leaked keys.
- Claiming push/calls coverage from a simulator run.
- Adding tests nobody asked for.
What it can do on your machine
Read from SKILL.md and the folder at commit 911b108. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
React Native >=0.77; Jest; @testing-library/react-native; Detox (e2e)
From compatibility in the SKILL.md frontmatter.
Context cost
Cometchat React Native Testing loads about 997 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 398 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Ground truth:
catalogs/rn-v5.json+catalogs/rn-sdk-v4.json. Build the feature; do NOT test it unless asked. Use this skill only when the developer asks for tests. Never add a test framework, e2e suite or CI to a project that did not request one.
Companion skills (read first)
cometchat-react-native-core— install, provider chain, init→login→render. Assumed, not repeated here.
Use this skill when
- "write tests for the chat screen" · "mock CometChat in Jest" · "add Detox coverage for chat"
Prerequisites & install
React Native ships Jest. Add the renderer:
npm install --save-dev @testing-library/react-nativeMock the SDK — never let a unit test hit the network
CometChat opens a websocket and needs real credentials. Mock at the module boundary:
jest.mock("@cometchat/chat-sdk-react-native", () => ({
CometChat: {
init: jest.fn().mockResolvedValue(true),
login: jest.fn().mockResolvedValue({ getUid: () => "test-uid" }),
logout: jest.fn().mockResolvedValue(true),
AppSettings: { SUBSCRIPTION_TYPE_ALL_USERS: "ALL_USERS" },
},
}));The UI Kit also pulls native modules, so mock the peers your test path touches —
react-native-gesture-handler, react-native-svg, react-native-video,
@react-native-async-storage/async-storage. Without them the failure is a NativeModule error that
never mentions CometChat: the same confusing shape as a missing install.
What is worth asserting
Ordering — the invariant most likely to regress: init resolves before login, and no chat
component renders until login resolves.
No Auth Key in source — a cheap grep test that stops a shipped secret ever landing:
it("has no auth key in source", () => {
const src = require("fs").readFileSync("src/config.ts", "utf8");
expect(src).not.toMatch(/authKey\s*:\s*["'][A-Za-z0-9]{20,}/);
});Wiring, not rendering — that onItemPress navigates, that onBack returns, that an opened
surface can be closed. Unwired affordances are the defect class worth catching.
Do not assert on kit internals — bubble markup, class names, child order. Those change between minors, so the test breaks with nothing actually wrong.

Detox for what only a device proves
| Flow | Why it cannot be a unit test |
|---|---|
| composer survives the keyboard | needs a real soft keyboard |
| hardware back navigates | needs the OS back gesture |
| gestures respond | proves GestureHandlerRootView is wired |
| release-build startup | catches the gesture-handler import-order crash |
Calls and push are outside Detox too — they need real hardware, real permissions and a second device. Record them as manual device checks rather than pretending they are automated.
CI
Jest with mocks runs anywhere. Detox needs a simulator — heavier, but feasible. Neither can verify calls or push, so a green CI run is not evidence that either works.
Common pitfalls
- Unmocked native peers — confusing NativeModule errors.
- Asserting kit internals — breaks on minor upgrades.
- Real credentials in tests — network flakes and leaked keys.
- Claiming push/calls coverage from a simulator run.
- Adding tests nobody asked for.
Verify it works
- Tests pass with no network access.
- No real credentials anywhere in the test tree.
